The liquid crystal display 1 further includes an upper polarizer 109 and a lower polarizer 110 respectively disposed on two sides of the liquid crystal display panel, wherein the upper polarizer 109 is adjacent to the upper substrate 1〇1, and the lower polarizer 1010 is adjacent to the bottom. The substrate 1〇2 and a backlight module 111 are used to provide a light to the liquid crystal display panel. Referring to Fig. 2, the alignment direction of the conventional alignment layer and the transmission axis direction of the polarizer are shown. The upper polarizer 1 〇 9 and the lower polarizer 110 respectively have a first transmission axis and a second transmission axis 202 ′, and the first alignment layer 106 and the second alignment layer 108 respectively have a first alignment direction 2 〇 3 And a first alignment direction 204. As shown in FIG. 2, the first alignment direction 203, the second alignment direction 2〇4 is perpendicular to each other, and forms an angle of 45 degrees with the side length of the liquid crystal display panel. The first transmission axis 201 is also opposite to the second. The penetration axes 2〇2 are perpendicular to each other, and the first alignment direction 203 is perpendicular to the first penetration axis 2〇1.

Since the first alignment direction 203 and the second alignment direction 2〇4 have a 45 degree inflammatory angle, the conventional liquid crystal display is at 45 degrees and 135 degrees. 225 degrees ' and 315 degrees have better viewing angle characteristics, but when the user is viewed from above, below, left, and right sides of the liquid crystal display, the visual range thereof is limited. In order to meet the usage habits of general users, the specifications for liquid crystal displays on the market focus on the horizontal and vertical viewing angle characteristics, and conventional twisted nematic liquid crystal displays are difficult to meet this condition.

The lanthanum system is disposed under the lower substrate 4〇2, and a backlight module m is used to provide a light of the liquid crystal display panel. 5(a) and 5(b) show the direction of the first transmission axis 5〇1 of the upper polarizer and the second penetration axis 502 of the lower polarizer, the first g of the first alignment layer The direction of the direction 5 〇 3 and the 7 1334943 second alignment layer of the second alignment direction 5 〇 4 . When the twisted nematic liquid crystal display is 0_m〇de, as shown in Fig. 5(a), the first alignment direction 5〇3 is a vertical direction, and the second alignment direction 5〇4 is a horizontal direction. The first transmission axis 5〇1 is perpendicular to the first alignment direction 5〇3, that is, a horizontal direction, and the second transmission axis 5〇2 is perpendicular to the second alignment direction 504, that is, a vertical direction. When the twisted nematic liquid crystal display is E-mode, as shown in FIG. 5(b), the first alignment direction 5〇3 is a vertical direction, and the second alignment direction 5〇4 is a horizontal direction. . The first transmission axis 501 is parallel to the first alignment direction 5〇3 and is also a vertical direction, and the second transmission axis So] is parallel to the second alignment direction 504 and is also a parallel direction. A feature of the twisted nematic liquid crystal display of the present invention, as shown in FIG. 4, that is, the upper polarizer 409 includes a diffusion layer 412' located on one side of the upper polarizer 4〇9 away from the upper substrate 401, and plural The circular particles 413 are dispersed in the diffusion layer 412. The thickness of the upper polarizer 409 is about 350 microns, the thickness of the diffusion layer 412 is less than 30 microns, and the diameter of the particles 413 is also less than 30 microns. Since the particles 433 have an internal diffusion effect, when the light passes through the lower polarizer 410 and When the liquid crystal layer 403 enters the upper polarizer 409, it is diffused by the particles 413. Therefore, gray scale inversion and color shift phenomenon can be avoided. 6 is a view showing a twisted nematic liquid crystal display according to a second embodiment of the present invention.

Rotating the light 'so the light cannot pass through the upper polarizer 6〇9. The difference between the liquid crystal display 600 and the liquid crystal display 400 of the first embodiment of the present invention is that the diffusion layer 612 is located between the upper polarizer 6〇9 and the upper substrate 6〇1. Since the particles 613 have an internal diffusion effect, when the light passes through the lower polarizer 610 and the liquid crystal layer 603 and enters the upper polarizer 609, it is diffused by the particles 613.

The lower polarizer 710 is disposed on the lower substrate. Below the 〇2, and a backlight module 711 is used to provide a light to the liquid crystal display panel. When there is no electric field between the common electrode 705 and the pixel electrode 707, as shown in Fig. 7, the electric field region 72a is not applied, the liquid crystal molecules are substantially parallel to the upper and lower substrates 7〇1, 702 'and thus the light passes through the liquid crystal molecules After the rotation, it can pass through the upper polarizer 7〇9. When the common electrode 7〇5 and the pixel electrode 7〇7 generate an electric field, as shown in FIG. 7 , the application of the electric field region 720b indicates that the liquid crystal molecules are rearranged and are substantially perpendicular to the upper and lower substrates 7〇1 and 7〇2. Rotating the light 'so the light cannot pass through the upper polarizer 7〇9. The difference between the liquid crystal display 7 and the first embodiment and the second embodiment of the present invention is that the upper polarizer 709 does not include a plurality of particles, and the color light layer 704 includes a plurality of circular particles 713. Therefore, when light passes through the lower polarizer 71 and the liquid crystal layer 7〇3 and enters the color filter layer 704, it is diffused by the plurality of circular particles 713. Figure 8 is a view showing the viewing angle of the twisted nematic liquid crystal display of the present invention. Since the alignment directions of the first alignment layer and the second alignment layer are respectively a horizontal direction and a vertical direction, the liquid crystal display of the present invention is Degrees, 9 degrees, 18 degrees, and 27 degrees have better viewing angle characteristics, that is, the user has a wider viewing range when viewed from parallel to the top, bottom, left, and right sides of the liquid crystal panel. 9 1334943 Fig. 1 is a cross-sectional view showing a structure of a conventional twisted nematic liquid crystal display.
